Agent Browser Guide — CLI First

Non-Negotiable Execution Contract

Follow this contract literally. Do not reinterpret it. Do not optimize it. Do not skip steps because the task looks simple.

1. Browser task detected → use this skill.
2. Browser task detected → use Bash only.
3. Bash command target → agent-browser only.
4. If agent-browser is missing → install it and wait.
5. After opening a page → run snapshot before any screenshot or visual reasoning.
6. After page-changing actions → run snapshot again.
7. If blocked → recover only with the procedures in this file.
8. If still blocked → use AskUserQuestion.
9. Without explicit user approval → never use WebSearch, WebFetch, Playwright, Puppeteer, Selenium, browser MCPs, or another website.
10. Before saying done → verify final state with snapshot, URL, title, text, or screenshot when visual validation is required.

If any step cannot be completed, stop at that step and ask the user. Never silently choose a different tool or source.
